4 2.5D Vertical Slice Modelling
Fig. 4.23 Exercise 19. Scenario 3. Distributions of (top panel) sea-level elevation, (middle panel)
density field, and (bottom panel) v-component of velocity after 30 days of simulation. Black lines
are density contours
This example illustrates the subtle way by which the ocean responds to wind
forcing. Equatorial countercurrents are an example of such exotic wind-driven
geostrophic flows.
4.6.7 Additional Exercises for the Reader
Repeat Scenario 1 of this exercise with a longer simulation time to explore whether
the pycnocline can outcrop at the sea surface, and if so, how this modifies the
dynamics. Repeat Scenario 3 of this exercise with the settings of τ o = −0.1 Pa
and τ 1 = 0.05 Pa in Eq. (4.25) and identify regions in which the geostrophic flow
runs opposite to the wind direction.
